Commit accb757d798c ("KVM: Move vcpu_load to arch-specifickvm_arch_vcpu_ioctl_run", 2017-12-04) added a "goto out"statement and an "out:" label to kvm_arch_vcpu_ioctl_run().Since the only "goto out" is inside a CONFIG_VSX block,compiling with CONFIG_VSX=n gives a warning that label "out"is defined but not used, and because arch/powerpc is compiledwith -Werror, that becomes a compile error that makes the kernelbuild fail.

In order to make the build succeed, this adds a #ifdef around the"out:" label. This is a minimal, ugly fix, to be replaced laterby a refactoring of the code. Since CONFIG_VSX depends onCONFIG_ALTIVEC, it is sufficient to use #ifdef CONFIG_ALTIVEC here.
